Q. What value of cc is a solution to this equation?\newlinec+17=20c + 17 = 20\newlineChoices:\newline(A)c=3c = 3\newline(B)c=5c = 5
  1. Isolate cc in equation: Step 11: Isolate cc in the equation.\newlineGiven equation: c+17=20c + 17 = 20.\newlineSubtract 1717 from both sides to isolate cc:\newlinec+17−17=20−17c + 17 - 17 = 20 - 17,\newlinec=3c = 3.
  2. Check solution by substitution: Step 22: Check the solution by substituting back into the original equation.\newlineSubstitute c=3c = 3 into the original equation:\newline3+17=203 + 17 = 20,\newline20=2020 = 20.
